DescriptionFirst massive Folsom spillway gate installed (14543916205).jpg | Workers install the largest piece of the first massive Tainter gate for the Folsom Dam auxiliary spillway in Folsom, Calif., June 25, 2014. The 179-ton steel gate is one of six Tainter gates that will control water flow from Folsom Lake into the new auxiliary spillway. The Tainter gates will rotate to control the flow of water through the dam. “We must lower these gates into place with a high level of precision and worksmanship to within one-sixteenth of an inch,” said David Neff, the U.S. Army Corps of Engineers’ design manager for this phase of project. “A gate that is not installed properly could leak and need repairs sooner than otherwise. We are trying to install something that will have a life expectancy of well over a century.” (U.S. Army photo by Capt. Michael N. Meyer/ Released) |
